Precision 3620 Workstations Continually Losing Wired Network Connection
Precision 3620 Workstations Continually Losing Wired Network Connection it will only work again if i restart the computer. running windows 11 pro
I work for a school district, and we have a lab with Precision 3620s Dentinal office programs. The problem we are experiencing is that throughout the day, many of these devices will lose network connection, getting the yellow triangle symbol on the Ethernet icon. Running diagnostics, it does not come up with any errors. Here is a summary of all we have tried so far:
Restarting the machines
Unplugging the network cable and reinserting
Changing network cords
Replacing the network switch for the lab
Updating firmware on the switch
Reinstalling Windows
Updating drivers
Replaced the network switch
After all of this, we are still experiencing this error. Has anyone had a similar experience, or know of any other possible solutions?

In Control Panel/Device Manager/Network Adapters right click on the Ethernet adapter. Under properties and Power Management make sure that allow the computer to turn off this device to save power is not checked. Also the information in this forum thread may help.

You're a better man than I am. I would have just turned my PC off and headed to the dinner table...!

Might be Windows Power settings. Try this on one of them to see if it helps, before you do all of them.
Open Device Manager and double-click the entry for your Ethernet adapter. Click its Power Management tab and uncheck the box "Allow PC to turn off...". Exit Device Manager.
Now navigate to the Advanced settings screen for your active Power plan. Disable Hibernation, Hybrid Sleep, and PCI Express Link State Management. And also set the Processor Power Management option to 100% for both Max and Min power settings. Save the changes and exit Power plan.
Now go to Start>Settings>System>Power & battery. On that screen, change the setting to Max Performance. (It's probably set to Balanced now.)
Reboot when done and see what happens...
EDIT: As usual @JOcean types faster than I do...!
